go-proptree

go-proptree provides a text tree view of nesting nodes with properties.

Building tree data structure easily, and you can add Icon, Tag and Description properties on each node.

Overview

This is example code of examples/01/main.go in this repository.

package main

import (
	"os"
	pt "github.com/bayashi/go-proptree"
)

func main() {
	tree := pt.Node("Root").Icon("*").Tag("tag")
	child := pt.Node("Child A").
		Description("This is a description about Child.").
		Description("You can set multiple lines.")
	tree.Append(child).
		Append(pt.Node("Child B").Description("This is a description about Child B."))
	child.Append(pt.Node("Grandchild").Icon("@"))
	tree.RenderAsText(os.Stdout)
}

It renders:

$ go run examples/01/main.go

┌* Root: tag
├─┬ Child A
│ │  This is a description about Child.
│ │  You can set multiple lines.
│ └──@ Grandchild
└── Child B
     This is a description about Child B.

Another tree from render_example_test.go.
